    摘要: A motion control design system implements a performance specification-oriented design approach. The system allows a designer to define desired performance specifications that are to be satisfied by a motion system, and determines tuning parameters (e.g., controller bandwidth and associated tuning parameters) that will yield performance within the defined performance specifications. An identification process identifies system parameters of interest based on collected system data. After the user has entered the desired performance specifications, an optimization process determines a range of bandwidths that will satisfy all specified performance requirements, and selects an optimal bandwidth within this range. A tuning process generates the corresponding tuning parameters for a systematically designed motion controller. Rather than using an optimal solver, the design system stores relationships between performance specifications and the major tuning parameter as matrices or mapping functions, given system parameters as inputs, making the design system suitable for embedded systems.

    摘要: Positional applicator devices and methods are for application of stretchable electronics relative to subsurface features of an object. In some embodiments, a positional applicator device for applying a stretchable electronic device to a surface of an object includes: a holder for a stretchable electronic device; a signal emitter positioned to direct an emitted signal toward a surface of an object; a receiver positioned to detect a return signal from the surface of the object; circuitry operably connected to the signal emitter and the receiver, the circuitry configured to compare the emitted signal with the return signal in order to identify surface and subsurface features of the object; circuitry configured to compare the identified features with a map of surface and subsurface features of the object stored in memory; and a positioner, the positioner structured to apply the stretchable electronic device to a position on the surface of the object.
